To all whom t may concern:

Be it known that we,.Gfno-Ren VV-Risparmia and CHRISTIAN HEILRATH, citizens .of `the United States, residing ,at Sacramento, in the county of Sacramento and State of Cali# fornia, have inveited certain new and useful lniprovements in Resilient Vehicle-Wheels, of which the following is a specification.y

Our invention-relates to improveinentsin resilient vehicle wheels, the invention being L designed as a substitute for and an improvenient on wheels dependingfortheir resiliency on pneumatic and other resilient tires,

the primary object ofthe invention beinito` eel provide a generally improved resilient w embodying the advantages of and eliminating the objections tov pneumatic tires, ,as well as objections now found .to resilient vehicle,wheels heretoforedesigned.

rl`he invention in its primary embodiment comprises hub and felly members connected to and movable relative to each other -by means of a connecting spring,.said hub and felly members being each provided with a pair of axially 'and ciicumferentiallymovable hub and felly plates, in the presentinstance in the form of disk plates, inclosing said springs and4 overlapping each otherintermediate said hub and felly members.

Asa means of limiting or controllingthe v axial. and circumferential movements of the hub and felly members and the disk plates carried thereby, said plates are provided .with

:stop mechanism, in the present instance,

located in the overlapping portions of'said thub and felly plates, and comprising, in the present instance, stop members or projec- Hally improvedfwheel. of :great strength and tions on the overlapping portions of vone .plate extending into and having a limited radial and circumferential movement in suitable stop openings arranged in tlieover-v .or adjacent -theimproved wheel, theimprovedwlieel also 'having itsparts so arranged and disposed relative to each otheras ytoprovide a gener- -modiiedform of wheel. i --Fig- 6, ,a similarI View Y.of a fiirther forni ormodi-cation of.stop ,mechanism stability havingthe requisite resiliency def'- sirediir this class of wheels.

A still fiirtherobjectis thel provision of,

N. improved hub land felly connecting springs together with improvedmeansof pivotally mounting and connecting the ends of said springs to thehub andfelly portions of the wheel.

A still further object is the provisionvof an improved h ub and felly lconnecting.; springembodying suitable spring connecting bearA ing memberspivotally connectedto the hub and felly portions and comprising a coiled spring connected to such bearing members and adapted to operate at all times, anda second compression spring connected to one of .said spi-ing connecting onbearing inem.- bers and adapted to be brought into engagement with -the opposite lspring connecting bgaring member underpi'edetermined loads or impulses -not ordinarily sustainedby the rst mentioned spring," the latter beingv .adapted tosiistain light loads while the compression springs are in the nature ofaiixiliary springs adaptedtobe brought into action-in sustaining heavy. loads asin the ,case of heavilyloaded trucks and other motor vehicles.

With thelabovefmentioned and other endsl in view, the invention consists in tlienovel construction,arrangement, and combination of parts, hereinafter described, illpstrated insome'pf its embodiments in the accom-' p'anying drawings, and particularly pointed -out-in the appended claims.

2. En a resilient vehicle Wheel, a resilient hub and ltelly connecting member comprising a tensionand compression spring provided at its ends with detachable pivot. bearing members, and a `compression spring attached to onef said bearing members and extending outside of said spring and adapted to engage with the other pivot bearing member When the latter is compressed to a pre-determined point by pre-determined loads.
